G.M. Automatic Transmission

Does anybody know the correct position for the magnet in the fluid pan of a G.M...THM400 auto gearbox. I changed the oil filter today and found a magnet in the pan,put it back where it came from, just wanted to check and make sure it's in the right place. TIA.

Martyn,
internal magnets are fitted to the lower pick-up pipe (submersed in fluid) to catch any metal particles, a jubilee clip to hold in place works fine, you should also have a magnetic pick up drain plug fitted as standard.

James, thanks for the reply,this box is like none other i have seen.There is no drain plug,got to drop the pan,the oil is sucked up through the filter,then through a pipe at the front of the valve chamber.The magnet (hollow middle)sits on a dimple on the bottom of the pan,and obviously being magnetic,sticks to the bottom of the pan.I'll take a chance it's right, i've done 15000 miles in it so it should be OK. Thanks for your help..... Martyn :thumb:
